Abstract
This presentation briefly discusses application of the Root Raised Cosine (RRC) pulse shaping in the
space telecommunication. Use of the RRC filtering (i.e.

Why JPEG
The compression ratio of lossless methods (e.g., Huffman,
Arithmetic, LZW) is not high enough for image and video
compression.
